Graveyard Desert

The episode is set in a rainshadow desert on the eastern side of Earth's only continent, 200 million years into the future. Wedged between this desert and the Global Ocean is a series of very tall mountain ranges which are tall enough to block even the most powerful storms. At this point in the future, there are no mammals, birds, reptiles or amphibians. The episode focuses on five species: (1) Bumblebeetle, a species of beetle that has been pushed to the edge of specialisation. They spend their lives searching for dead flish which are a good food source for their young. (2) Desert Hopper, a bizarre rabbit-sized cone snail that hops about on one muscular foot. They tend to bury themselves during the heat of the day and only come out at the cool of the night. (3) Deathbottle, a carnivorous plant, that has traps to feed on the Desert Hoppers. (4) Flish, shown dead, animal from the previous episode. (5) Grimworm, a worm, live inside dead Ocean Flish body and scavenging it.
